The LED backlight screen has been displayed frequently in the market currently. This screen is the application which developed slowest among the three application of LED backlight. It is predicated that the permeability of LED backlight screen could not reach one percent in 2009, but it will increase to thirty five percent in the year of 2012.

The technology of LED backlight has been applied for the screen very early. But the product has not gained the good sales achievement, because it had the shortage of color homogeneity and the price is high. The value of the LED backlight becomes more and more obvious with the development of the light source technology. Many manufacturers are joining the development of the related screen, and releasing their own products. Many top manufacturers are also applied this technology into the display. Although many corporations are arranging the LED backlight products, their core business has not turned to the screen. Price is still the main obstacle.

The panel developers hold the optimistic attitude toward the related screen research. Some experts say 2010 will be the year which the related screen starts popular. Most of the screen cost is come from the liquid crystal panel. A liquid crystal display needs dozens of LED which will cost thirty to sixty US dollar, while the cold cathode fluorescent light only costs a dozen of US dollar. The cost reduction of dozens of US dollars will have a large influence on the screen market. The large production of the LED panel will reduce the cost of LED. Some manufacturers are developing the cheaper model group, even some of them declaim that the price of LED model group will decrease to the price of cold cathode fluorescent light model group.

The LED screen will not be popularized widely in the short time from the cost point of view. It is predicated that the price of LED will decline from the large production in the latter half of 2010. It is predicated that thirty five percent of the display panel will apply the LED backlight model group in the year of 2012. The related integrated circuit is P4KE13CA.

The television market continually changes. This year has brought the release of the first 3D televisions on sale. This is shortly after the release of LED technology for televisions. Before discussing the available LED TV bracket and LED TV wall bracket choices one must first understand the LED television. What is it and what makes it different from your typical LCD television?

LED is a type of light which has been around for several years. The light bulb has a longer life than your typical light. The first thing we saw light emitting diodes with was Christmas lights. Samsung, Panasonic, Philips, Toshiba, LG, ProScan, and Vizio have all decided to offer LED TVs. The technology has replaced the traditional fluorescent light found in LCD televisions. LEDs have two forms: a Dynamic RGB and a White Edge LED. The RGB method provides truer colours like black, white and primary colours. It has a higher dynamic and costs less. The Edge LEDs have a diffused light across the entire screen sharpening the backlight, but also causing a dimming of the picture.

As you might have guessed by now the LED technology is nothing new. The use in televisions was new and it rose in popularity rather quickly. The reason they became so popular was because most understood the LED light would last longer than fluorescent light for the backlighting. They figured it was better technology and therefore worthy of spending a little more. The downside in the popularity of LCD televisions is that the off angle viewing is poor. Even offering LED with the LCD technology has not changed this. However, LCD is still better than the plasma design because it is based off of light rather than a plasma creation which has a half life.

At the moment the LED technology has not quite reached its potential, but for those who follow the electronic industry this has not made them less popular. In 2010 more models have been released in small screen sizes. LG has over four models you can purchase as do many of the aforementioned producers of LED technology.

Now that you have an understanding of what LED televisions are and that they are being sought by the public you can look at the LED TV bracket and LED TV wall bracket available for these televisions. As a flat panel screen this TV can be tipped over and damaged if it is not correctly mounted to a wall with the TV bracket.

LED TVs are not unlike the regular LCD with fluorescent light. You can use similar TV brackets with the LED television. However, it is best to shop for an LED TV bracket or LED TV wall bracket. The reason for this is that you have the right size. You always want to have the proper bracket no matter the television you own. Therefore, you can look at the two choices you have. You have the TV bracket which is standard in how it works. It will mount your television safely to the wall or TV stand you have chosen. It will not have a lot of manoeuvrability when it comes to the tilt or swivel. It is mostly a steady wall mount for direct angles.

The second choice you have is the ultra slim bracket. The ultra slim bracket comes in two ranges: 26 to 32 inches and 37 to 65 inches. They were created for this range because up until 2010 small sized LED TVs were not being manufactured. Now you have some companies offering below 30 inches.

The ultra slim bracket is not like your typical LCD television bracket. It offers four screws for the smaller size screens, but it is in a horizontal position rather than a square. There are two silver brackets for screws and then two black brackets. You can manipulate the size a little bit on the ultra slim bracket. It is not a huge metal bracket, which makes it lighter and to some degree easier to install.

For those who require an LED TV bracket the ultra slim can be the most attractive. It will be a little more than the regular LED TV bracket which is designed like most LCD brackets. The good attribute of LED TV bracket options like the ultra slim is that it can make the TV almost flush with the wall like a picture frame.

I have used this TV for a week now. I ordered it from Amazon, but shipped by Audio and Video Center. I now use it in India.

First, about the vendor who sold the TV. I had never even heard about Audio and Video Center, but they were offering the best price on Amazon for this TV. I called them a couple of times to verify the price and how/when they would be shipping the item. Their customer service folks were courteous and informative, and they shipped the item the same day I ordered on Amazon. It arrived some 3 days later in top-notch condition. I would use them again, and I have put them on my list of trustworthy online retailers.

Now, about the TV. I was looking at both LED-lit LCD as well as plasma models. I would have picked up a direct LED backlight LCD TV, but I couldn’t find any in the 60″ range. The reviews of edge-lit LED TVs all mentioned issues of uneven backlighting and black-level deficiencies. The plasmas I looked at on the other hand had high power consumption (almost twice that of regular LCDs) and were heavier by 30% – 40%. Plasmas also seemed more fragile during shipping – I saw a number of cases of cracked front panel being reported, which was not good for me (as I wanted to move the TV to India). Overall, I was looking for a TV with great picture quality at a reasonable price in the 60″ range, and I took a leap of faith on this Sharp model based on the (few) reviews I had read here in Amazon and elsewhere.

I am glad to say that so far I have found the TV to be extremely good – true to the reviews I had read. It still needs a few refinements, and I would have given it a 4-1/2 star rating if possible. Spefically, the good parts:

- Picture quality: It took me some time to tweak the settings and get the kind of picture I like, but the end result is excellent. With 1080p 24Hz sources (blu-ray movies), the picture is outstanding, with deep enough blacks, natural colors and even backlighting. I do not notice any 3D effect, but even at low backlight settings, the picture is bright enough for me. I have since gone to local stores and looked at edge-lit LED TVs (Sony, Samsung, etc, set to showroom level super-bright pictures). I feel that the PQ of this TV is no less in comparison.

- User interface: Is elegant and simple. There are many settings to manage the PQ and there are several pre-defined A/V modes. You’re most likely to be happy with one of the pre-defined modes with some tweaking. I found it useful to both use the settings on the TV and those on the Blu-ray player to get the optimum quality for my tastes.

- Power: The TV can be set in automatic power save mode, which adjusts the backlighting based on ambient light. This works well most of the time. The rated power consumption is 390W at the highest level, and I think most of the time you’ll be using much less than this. You can also set the TV to turn off automatically based on no input signal or no activity.

- Advanced features: Active Contrast (which automatically adjusts picture contrast based on the scene) is very useful. I don’t find any visible improvements with the 240Hz “Fine Motion” setting. The picture is generally smooth, and where there is very minor motion blur, the 240Hz setting doesn’t seem to help. A number of color adjustment settings are given, which one finds best to leave at default values. The “Film Mode” setting – in conjunction with a 1080p 24Hz source – seems to produce smooth picture.

- Panel: The X-gen panel in this TV is dark black (not grayish). This is a different kind of panel than the one in my 4-year old Sony Bravia, which doesn’t reflect any light at all. The Sharp panel does reflect some light, but not anywhere close to plasma glass panels. I haven’t found this to be an issue, even though the TV is in a room with a lot of ambient light (large windows and glass patio doors).

- Looks: With the dark black panel, the piano-black glossy frame, and the (color-matched) sturdy stand, it looks very nice and classy when it’s not running. The speker positioning makes the frame looks slim. The back of the TV is also nicely rounded and very slim.

- Remote: Remote is pre-programmed, universal type, with minimalistic design. Nothing extraordinary about it. Some keys can be lit by pressing a “light” button.

- Unexpected bonus: This TV supports the PAL color system for two of its (composite) video inputs. This is a great feature for me to have in India, where the cable and satellite programming is in PAL. Another bonus is an excellent comb filter, which shows clear picture even with composite video input (which is the case with my satellite box). The TV, however, doesn’t have univeral power supply (100-240V), which would have been nice. I have to use a step-down transformer (240 to 120V), but otherwise the TV works fine.

Now for the areas where more work is needed from Sharp:

- Picture: Although Sharp claims a wide viewing angle – and many people have said that the viewing angle on this TV is better than the Sony EX models – the black level does get affected as you move from the exact straight line from the TV. Specifically, you can see the picture getting lighter even from a few degrees to the side. This is not a big concern in a family room setting, but the folks sitting right opposite get the best picture as per your setting. Also, in a fully dark room, you can see the border areas around the movie frame as grayish. In other words, the black levels are best with some ambient lighting and not in a dark room (perhaps as to be expected in a LCD TV).

- Sound: The TV’s sound output is weak, but usable in a moderate sized room. There is no bass at all to speak of, and the audio settings like simulated surround and bass enhancer are useless. The speakers in this TV are recessed (behind the frame and down-firing), and this doesn’t help the cause of good audio either. I use the TV’s speakers only when watching Satellite programming, and find it to be tolerable.

- Build quality: While the stand is solid, and the back is well-done, the frame has a loose feelng when you press it (with some movement). Sharp could have done this better.

- Lack of swivel: This TV cannot be swivelled to suit your sitting position. This is a drawback due to the picture issue mentioned above.

- No S video input: A minor irritant. But with the excellent processing of composite video signals, this doesn’t seem to be a big issue.

- No earthing in power cord. Not sure if this is a problem. The power cord supplied is also very short.
